Last week’s forecast played out close to main weather model predictions.
We definitely saw cooler and unsettled conditions as a large low tracking well to our north pushed clouds and scattered showers and thundershowers, along with cooler temperatures, into our region. The forecast ended with uncertainty as to whether warmer temperatures would move in.
Guess what? This forecast period looks to begin on the warm side, with warmer temperatures lasting right through.

Thunderstorms and straight-line winds
Straight-line winds in thunderstorms can cause as much damage as a tornado and are next on our weather school list exploring how and why severe summer weather forms.
Unfortunately, I must start this forecast on a sad note. If you have not already noticed, the usual temperature ranges for this time of year have peaked and are starting to go down.
That said, it looks like we will kick off this forecast period a little on the wet side as an area of low-pressure tracks through the central Prairies, bringing with it clouds, showers and thunderstorms on Wednesday and Thursday.
Exact timing and placement are a little uncertain, but the way this year has been going, it seems almost every cloud tries to drop a little rain.
Temperatures look to be warm, as southern regions will stay in the sector south of the low. Expect daytime highs in the upper 20s to around 30C, with overnight lows falling into the upper teens.
High pressure will build behind this low, bringing mainly sunny skies and slightly cooler temperatures to our region Friday and Saturday. As this high slides east, a developing area of low pressure to our west will set the stage for very warm and windy conditions on Sunday and Monday. Expect strong south winds, which will help push daytime highs into the low 30s.
Combine this with higher humidity and it will definitely feel hot, even with the strong winds. As the western low slides by, we could see some thunderstorms, but confidence is low in the potential for these storms.
Once that low has passed, we will once again see high pressure build in. This high will bring a return to sunshine and seasonable temperatures, with daytime highs in the low- to mid-20s and overnight lows falling into the low teens.
Usual temperature range for this period: highs, 20 to 30 C; lows, 10 to 16 C.
